I am running the free appentice version on my Lifebook (Fujitsu) 5010 tablet. I have a modified open gl video card. When I open Houdini I get this message:

Warning: OpenGL shader extensions not available.
This is a limitation of your video card
or driver, and will prevent Houdini from
using GLSL shaders.
Set the HOUDINI_OGL_ENABLE_SHADERS
environment variable to zero to avoid
attempts to use this extension.

How do I do this? Thanks for any help.

In your Houdini documents folder, the same folder that the scene and renderoutput folders are in, there should be a file called houdini.env. Open it in notepad and add “HOUDINI_OGL_ENABLE_SHADERS = 0” (without quotes) to the end of it.

See

http://en.wikipedia.org/wiki/Environment_variables [en.wikipedia.org]

Specifically the bit that says “The most common method of setting an environment variable in Windows is via <Control Panelystem:Advanced:Environment Variables>”.

Not being a programmer, I noticed in the .env file there was a “#” at the beginning of every sentence.

I did not use the # when I entered “HOUDINI_OGL_ENABLE_SHADERS = 0” not the quotes. Was this the correct way to enter it?

Sorry to sound like such a novice.

Never used Houdini before…I have owned 3ds Max since version 1,including 2010…but wanted to give Houdini a try.

Thanks for the help…and any further instructions if I got it wrong.

You were correct in not using a #.
If there is a # before any line Houdini ignores it.

Thanks
